SANDY S. SORRENTI, OF SAN FRANCISCO, CALIFORNIA.

DOOR-OPERATING MECHANISM.

To all whom it may concern:

Be it known that I, SANDY, S. SORRENTI,

a subjectvof the King of Italy, residing at San Francisco, in, thecounty of San Francisco and State of California, have invented certainnew and useful Improvements in Door-OperatingMechanisms; and-I do herebydeclarethe following to be afull, clear, and exact description of theinvention, such as will enable others skilled in the art' to which itappertains; to make and use the same. v I

This invention relates to a car door opener, vention is the provision ofa novel type of operating mechanism which cally move the door toclosingposition, when the car'is started in motion, and will automatically movethe. door to open position when the .car is brought to a stop.

Another object of the invention is the provision of door operatingmechanism, for carrying out the above object, and which will be ofsimple, and durable construction, efficient in operation, and which isparticularly adapted to be applied toa street railway car of the typewherein the door has to be operated by one ofthe crew, so as to admit ofthe automatic operation of the door. l v

Other objects will. appear and be better understood from that embodimentof my invention of which the following is a specifi cation, referencebeing had to the accompanying drawings forming a part thereof,

Application filed August 8, 1916. Serial No. 112,972.

Fig. 6 is a longitudinal sectional view,-. taken on the line 6-6 of Fig.3.

Referring to the drawings in detail, the letter A designates the frontend of a street car having a vdoor opening B, on the side thereof,adapted to be closed by a'slidable door C, which when in opened positionis adapted to be received by a compartment D.

Depending from the under side of the platform of the car, and located ata point near the adjacent car truck, is a pair of hangersl, in which arejournaled the opposite ends ofa shaft 2. A pulley 3 is keyed on theshaft 2 and a belt 4 passes around the pulley 3 and around a similarpulley, not shown, mounted on the axle of theadjacent car truck, so asto cause rotation of the shaft 2 when the axle is rotated. A. bevel'gear5 is keyed to the shaft 2 at a point adjacent the pulley 3, and the saidgear 5 meshes with a smaller gear 6, carried by one end of a shaft 7.The shaft 7 extends, at right angles to.the shaft 2 and is journaled inbrackets or hangers 8, which depend from the under side of the platformof the car, and the opposite or outer end of the shaft 7 carries a bevelgear 9 ofthe size of the gear 6.

Extending at right angles to the shaft 7 is another shaft 12. This shaft12 is telescopically associated with a sleeve 11. The shaft 12 isthreaded for engagement with the threads 13 formed in the'sleeve 11. The

under side of the car platform, and arranged in spaced relation with thebracket 14, and the sleeve 11 has that end through which the shaft 12passes provided with a head 17 adapted, when the sleeve 11 is moved in adirection away from the bracket let to engage the bracket 16 and limitthe sliding movement of the sleeve 11. The sleeve 11 has that endopposite the one provided with cured thereto by means --of fastening:eleT- merits 27." p p The cylindrical body 21 hasthe'l 'end op' end of"a linlt'28. Theoppositev end time link 28 has pivotal connection withoneend of another link 29, an'd the 'opposite' end bf the: latter linkis secured tO' OHBBDd Of a shaft-30 which extends at right angles r to lthevsha ft '12, the sleeve 11 and the cylindri cal'body 21",andtheothenend of the 30 haskeyedtheretoa bevel gear-31:

A 'shaft'32 extends at right angles" to the shaft30 and is journale'd inhangers de pending fr'om the under" sideof the i "plat 1 form'ofth'ecaiyand'one end of the shaft32 carries' a bevel gear'BL 'Whichmeshes with the gear 31' carriedby the shaft 80;and the" other end-" 0fthe shaft 32 has connection with the lower end of an incline'dro'd 35",the upper'end of'which' rod isconneoted'- to'th door Ci b When the earis started the belt 43 will-"im fl partrotation to the shaft 2, and thelatter in turn will, through the mediumof"the'* shaft 7,'ca'use rotationof the shaft '12,cau'sing the 'sleeve '11 to be moved 'in thej'direetinnwf the bracket-16, andcause' the "body 21' torockthe-links 28and-29*int0 the posi-if tion-showd in Fig 4L, thereby imparting 1rtat-ion to the shaft '30, and resiil'ting inrota tion of "the"shaft 32and the forward rock ing lrof' the" rod 35 'tothe position shown; Brig.-lfso as to niovethedoorto 'c'ldsed po sition."

It is to 'be "understood that the threads on the inner surface of thesleeve-11 and the shaft 12 are of "such pitch that one revolu tio'nof'the shaft-l2 will cause the'sleeve 11' to "travelisufi iently "tobring; the head 17 into] engagement with "the bracket 16,'so tolimitthe"sliding'movement of the sleeve 11,? and itfwill also be noted thatthe length: of the "threaded portions on the inner surface "of thesleeve 11 and on the shaft 12 ment with the bracket16'the outerjendofthe threaded portion" on the sleeve 11' and are such that whenthe head"17 is in engage' the inner end of the threaded portion of the shaft 12arein engagement inview thereof, and asthe bracket- 16 prevents endwisebut not rotary movement of the sleeve 11 the sleeve will rotate with theshaft 12, holding the doorG 'inclosed' positioni It is also to beunderstood that the rocking of the links 28'ai'1d 29am cause the shaft30 to rotate in an arc sufiiciently to cause about a quarter of arevolution of the shaft 32, whichwill besufEci'entito mozve the door 0to closed position. A weight 36 is carried'byfthe outer end' of f adepending arm 37'ywhich is carried by the shaft 32; and w-hen 'the 1shaft 32 has been operated- 'tocloseithe door: C, the weight 86 positethe one-whioh carriesthe 'fiange 23 i bifu1'cated,'= and pivotedbetween-"the fingers i of the bifurcatedend of-the -bodyj2l is one andarm T 37 will be' moved upwardly to a horizontal position.

During the rotation 'ofjthe weight 36%6'1101 mal position the rod 35will be'moved- 'reais wardly "from the position *shown in Fig.- -'1,-= 90' and open the-door.
